I have two load-balanced SUN servers one with 4 GB RAM and 3 CPUS, the other one with 1GB and Two CPUS. I will 20 for first server and 15 on second one.

Can some suggest me what should be the value > of $max_servers and $max_requests. The $max_requests is non-critical, just keep a default (10 or 20 or 50 is fine). $max_servers is the crucial performance knob. Too small and the machine is underutilized, too much and you end up with overbooked memory and swapping. It depends how powerful CPU is, how much memory is available, how many messages per hour, and what SA network tests you have enabled. If memory is not a problem (e.g. 1 GB), without long-latency SA network tests enabled a number would be 5 to 10. With high-latency network tests and particularly with Razor (and when you see the machine is underutilized and there are messages waiting to be processes) you may need to bump up the value to 20 or even 30, if there is sufficient memory available and you need to squeeze most of the box. I would say for 4000 users a value between 5 and 10 would be a good starting point. With low memory (e.g. 256 MB) a value of 2 or 3 would probably do.
